• Seeking help on deciphering if this is code that makes sense on a C64

    From Sanford Dickert@3:770/3 to All on Fri Feb 5 17:18:21 2021
    Hey all -

    Long time since I played with a C64 (and this is going back to 1982, mind you).

    I have a screenshot of what looks like a dump of binary before starting up in a C64 screen. Have any of you seen something like this? Do you know what the columns mean or what they could be signifying?

    I "think" the last column is the value column (8-bits) and the 2-5 columns MAY be the address spec (2+4+4+6) but I can not be sure since I do not know if the emulator will make it work.

    And the first column - no clue.

    The data is here: http://bit.ly/wvbins01ep05
    And the screenshot is here: https://preview.redd.it/yl52isqrtmf61.jpg?width=960&crop=smart&auto=webp&s=c6d5355ad9f50fd84c56a984bcc9f568f743dbc9

    Any help would be very much appreciated!

    Thanks!

    Sanford

    Which is junk. Interestingly the 3 BRK's at the end, is the only sequential part.

    Already line 3. Why would someone want to OR the accumulator twice
    without using the result after the first time?

    This for sure is no real assembler code like Andreas already outlined. There is no sense in this code at all.

    Is this screenshot taken from a movie?

    Chances are that these are just random numbers. If it is taken from a movie then in theory there could be an easter egg to find here but unless there is some "evidence" this is something worth looking into, I would not really waste my time deciphering
    something where there might be nothing to be deciphered in the first place.

    It’s from episode 5 of Wandavision (Disney+).
    Vision is working in an office with several C64s. This screen is displayed with modem sounds as the computer connects to the Internet.

    For a deeper dive into the scene and the screenshot, watch Robin Harbron’s video on his 8-Bit Show & Tell Channel:
